Everything flawless, except heating
The location, cleanliness of the hotel and the staff was top notch, I wouldn't ask for more. They were very kind and helpful. The only issue we've had was that the hotel does not have a heating system other than the AC in the rooms. I found it a bit strange, considering Amsterdam is a very cold city, especially during winter and AC is both not healthy and not as efficient. Our room was very cold the first day, it warmed up by 2nd day however dried up the air in the room so much that affected our breathing.
Apart from the heating, our experience with the Albus was perfect.
